Chickens should pay attention to the identification of these respiratory diseases

No matter which respiratory disease occurs, it is difficult to determine which respiratory disease occurs from the clinical symptoms and the performance of chickens, which brings some difficulties to the diagnosis. In order to help you make a preliminary diagnosis on the spot, various respiratory diseases and common diseases with symptoms of respiratory diseases are introduced as follows:

Chronic respiratory diseases in chickens

The disease is a respiratory disease caused by Mycoplasma gallisepticum. Mycoplasma is widely found in chickens. It can be said that in all kinds of commercial laying hens, a certain proportion of chickens carry this pathogen. However, under normal circumstances, when no other diseases occur, this mycoplasma will not cause disease in chickens. Therefore, mycoplasma can cause chicken disease, must have certain conditions, or must be under the action of a variety of stress factors, can occur.

Infectious bronchitis

The disease can occur in chickens of all ages, but it occurs more frequently in chicks and adult chickens. The disease is caused by a virus. It is characterized by acute onset and rapid spread. There are three types of this disease, namely, respiratory type, kidney type and glandular stomach type.

Chicken infectious rhinitis

It is a disease caused by a bacterium called Haemophilus parachuis. Chickens of any age can occur, but breeding chickens and laying hens are common. The disease is easy to occur in cold seasons. Once it happens and spreads quickly, the whole group can be involved in a few days. None of the chickens of the right age in a chicken farm were spared. Diseased chickens have secretions in the nasal cavity, which are common to flick the nose.

Chicken Newcastle disease

Although the disease is not a respiratory disease, but the occurrence of Newcastle disease is more common, especially the occurrence of atypical Newcastle disease, with obvious respiratory symptoms. At this time, if Newcastle disease is misdiagnosed as other respiratory diseases (such things often occur in actual production), it will cause great losses. Therefore, when chickens have respiratory symptoms, the idea of diagnosis should be to consider whether it is other respiratory diseases after the exclusion of Newcastle disease.
